目的：观察血管内径与动脉流速对动静脉内瘘流量的影响。方法：纳入内瘘术患者62例，根据动静脉内径（diameter， d）（A组：d ≤1．5 mm，B组：1．5 mm ＜ d ≤2．0 mm，C组：2．0 mm ＜ d ≤3．0 mm，D组：d ＞3．0 mm）；动脉流速（velocity，v）（a组：v ≤20 cm／s，b组：20 cm／s ＜ v ≤50 cm／s，c组：50 cm／s ＜v ≤100 cm／s，d组：v ＞100 cm／s）分组，比较各组术后2个月内瘘流量及透析流量。结果：A组、a组手术失败风险高，且内瘘流量及透析流量分别小于B组及b组（P ＜0．05）。静脉内径分组间，仅B组和C组间在透析流量方面差异有显著性（P ＜0．05）；其余各组间内瘘流量无明显差异。结论：动脉内径≤1．5 mm、动脉流速≤20 cm／s者，不适宜行动静脉内瘘术；随着动脉内径增粗或者动脉流速增快，内瘘自然流量及透析流量均升高；静脉内径对内瘘流量无显著影响。

Objective To investigate the effect of vascular inner diameter and artery flow velocity on the flow of internal arteriovenous fistula. Methods Sixty-two patients received the operation of internal fistula were enrolled. According to the inner diameter (Group A: d ≤ 1.5 mm, Group B: 1.5 mm < d ≤ 2.0 mm, Group C: 2.0 mm < d ≤ 3.0 mm, Group D: d > 3.0 mm), the patients were divided into four groups in terms of artery flow velocity (Group a: v ≤ 20 cm/s, Group b:20 cm/s < v≤50 cm/s, Group c:50 cm/s < v ≤ 100 cm/s, Group d:v > 100 cm/s), the differences of fistula and dialysis flow for two months were analyzed among various groups. Results Compared with Group B/b, patients in Group A/a had higher risk of operation failure, with lowered inner fistula flow and dialysis flow. In terms of inner venous diameter , there were significant differences between Group B and C. Conclusions It is not recommended to carry out the inner vascular fistula operation. Followed with the thickening and increasing of inner artery diameter and artery flow , the inner fistula flow and the dialysis flow increase. The inner venous diameter has no significant impact on the inner fistula flow.
